Technical field
The present invention relates to the preparing methods and system of the free index of stock, and in particular, to the index of an investment instrument
The establishment of the index of establishment and analysis method more particularly to Shanghai and Shenzhen A-share and analysis method.
Background technique
Cognition of the mankind for stock market's moving law is an extremely challenging world-class problem.So far, do not have still
There is any theory and method can be convincing and stand time check, people often combine many factors, packet
Technological side, basic side are included to predict stock future trend.Currently most knowledgeable for speculation in stocks user is exactly Index of Shanghai Stock Exchange, foundation
The prediction and analysis of the common indexs such as plate, some specific plate index, but these are all based on the whole city or some field (plate
Block) specific analysis, owner can only react the stock later period tendency in each market it is seen that a thing on the whole,
The stock being concerned about with user itself there is no contacting too much, if user wonders that the following situation of oneself stock also needs individually
The stock for analyzing oneself is upper card or GEM, and the stock of oneself, this analysis are then analyzed by way of sitting in the right seat
Method is often not intuitive enough, and also reacting with real market has certain gap.
The birth of free index allows each user to have an one's own index, passes through comparative analysis index history
Tendency and the comparison index and other market indexes can more intuitively reflect user currently most concerned about the tendency of stock, and lead to
The technical indicators such as excessive valence predict future trend.Currently on the market there are no any one for user's self-selected stock indexing
Analysis method, the case that also user's self-selected stock attention rate behavior is not worked out as weight are mainly currently on the market
The concept in stock pond, only counts earning rate, and the quality of self-selected stock, too unilateral, several factors are assessed only by earning rate
It does not account for, user adds free behavior relatively random, if cannot cannot really react in conjunction with the usage behavior of user
The shares changing tendency of user's concern out, can not predict future trend by the morphology techniques index of long-term K line, free index
Birth just solves a series of relevant issues, provides unique self-selected stock analysis method for user.
Such as Index of Shanghai Stock Exchange, plate index for occurring in the market etc..The Shanghai composite index is with the distribution capital stock number of constituent stocks
It is weighted for flexible strategy, calculation formula are as follows: report phase index=(total market capitalisation/base periods of report period constituent stocks) × base period refers to
It counts wherein, total market capitalisation=Σ (share price × distribution number of share of stock).Index of Shanghai Stock Exchange series is real-time calculating, is gathered in each day of trade competing
After valence, opening quotation index is calculated with the stock opening price (no conclusion of the business person takes yesterday closing price) that aggregate auction generates, later per big
An index is recalculated within about 2 seconds, until closing quotation, the publication outward in real time per about 6 seconds.The wherein calculating price of each constituent stocks
(X) it is determined according to following principle: if the same day does not strike a bargain, X=day before yesterday closing price；If there are conclusion of the business, the newest conclusion of the business of X=on the same day
Valence.Component stock is relatively fixed constant, the calculating of Index of Shanghai Stock Exchange and shows, lack individuality unrelated with user behavior.

Example.
As shown in Figure 1, the invention discloses a kind of preparation method of free index, it is daily to self-selected stock by analysis user
Attention rate, and combine user itself self-selected stock a set of novel index for compiling of amount of increase and amount of decrease situation and corresponding analysis side
Method, the preparation method of free index the following steps are included:
Define self-selected stock range step: definition participates in the self-selected stock range of free index establishment；The self-selected stock range is
Refer to that the component stock of statistics is only limitted to Shanghai and Shenzhen A-share, this block also can further be expanded into B strands, stock in America, Hong Kong stock etc., count in this way
Range is just wider, such as user has 20 self-selected stocks, there is 10 A-shares, 5 Hong Kong stocks, 5 stock in Americas, at this time when the range of definition, this hair
The case where 10 A-shares of bright consideration；
Intelligent treatment step: ingredient equity is obtained using user's self-selected stock as component stock according to the self-selected stock range
Weight, radix value；It calculates day free index step: according to stock index, component stock weight, radix value, calculating day free finger
Number, the radix value is as the referential data for calculating day free index for the first time.
Wherein, Intelligent treatment step includes that range step, the acquisition effective click data of user's self-selected stock are effectively clicked in definition
Step calculates user's self-selected stock day attention rate step, calculating composition stock weight step, the base period numerical value step for defining free index
Suddenly, the content in elaboration Intelligent treatment step more particularly below.
Range step is effectively clicked in definition: effective click range of the self-selected stock within the scope of the self-selected stock is defined, it is described
Effectively clicking range is to reject the click that user arbitrarily clicks and/or the click of nontransaction time obtains later, is denoted as effective click
Data；
Acquisition user's self-selected stock effectively clicks data step: single branch stock within the scope of acquisition single user's self-selected stock is in list
Effective click data of a day of trade is denoted as day effective click data of user's self-selected stock, and the day of all users is effective
Click data is uploaded to server；Preferably, nearest h day of trade user is counted according to the self-selected stock slice of daily each user
Daily corresponding millions of effective click datas of user are uploaded to server-side as calculating user's attention rate by effective click data
Measurement；The click for referring to and rejecting noise stock is effectively clicked, the click statistics of nontransaction time is rejected.Noise stock definition: user
Arbitrarily browsing, is not subjective approval, it is assumed that given threshold 3, to single stock (being only limitted to A-share).User passes through " self-selected stock row
The stock number 10 of feelings list " sequence browsing, when being greater than 3, then hits take 10；User is 2 by search stock number, is passed through
Other entrance numbers of clicks are 1 etc., and the noise data less than threshold value 3 will not count.The present invention only considers user from free
The click statistics that stock list enters, and the click lower than 3 times does not count.System is sliced according to the self-selected stock of daily each user
The effective click data of nearest 5 day of trade user is counted, daily corresponding millions of effective click datas of user are uploaded to service
It holds as the measurement for calculating user's attention rate.
It calculates user's self-selected stock day attention rate step: user's self-selected stock is calculated according to the day effective click data adduction
Day attention rate；Calculating composition stock weight step: using user's self-selected stock as component stock, share split is calculated as according to the day attention rate
Weight；It defines the base period numerical steps of free index: defining the radix value of self-selected stock, the radix value is Fixed constant
Value；Calculate day free index step: according to stock index, component stock weight calculation day free index.Such as the specific T of calculating
When day free index, used according to the attention rate of amount of increase and amount of decrease situation combination user's self-selected stock on the component stock same day and weight calculation T days
The free stock index in family.The present invention is analyzed by the index contrast between Index of Shanghai Stock Exchange and user, can intuitively be reflected very much
The combination tendency of the most concerned self-selected stock of user selects stocks for investor and enriches investment reference.
Specifically, the self-selected stock range is the Shanghai and Shenzhen A-share in user's self-selected stock.Preferably, the range refers to
The component stock of statistics is only limitted to the Shanghai and Shenzhen A-share in user's self-selected stock.
Specifically, the determination method that the user arbitrarily clicks is, by setting fixed threshold, to user in stock list
In be less than the click of the fixed threshold to the number of clicks of single stock, be denoted as user and arbitrarily click.Effectively click, which refers to, picks
Except the click of noise stock in user behavior, the click statistics of nontransaction time is rejected.The click of noise stock refers to that user is arbitrarily clear
Look at, be not the subjective invalid clicks approved, in specific implementation, can given threshold K the single branch stock for being only limitted to A-share is used
Following methods are counted, and in the displayed page of front end, as the stock number A that user is browsed by " market list " sequence, work as A
When < k, A:=0；Otherwise, A:=A；User passes through the stock number B that " data center " browses, as B < k, B:=0；Otherwise, B:
=B；The stock number C that user is browsed by " intelligently selecting stocks " is as C < k, C:=0；Otherwise, C:=C；User passes through " information "
The stock number D of browsing, as D < k, D:=0；Otherwise, D:=D；User passes through the stock number E that " search " browses, as E < k
When, E:=0；Otherwise, E:=E.Symbol: the meaning of=expression assignment.
Specifically, it is described calculate user's self-selected stock day attention rate step described in user's self-selected stock day attention rate calculating
Method is as follows:
In formula, Att (h, i) indicate on T, to i-th of stock h-th of day of trade day attention rate；Gi is that stock i exists
The summation of effective click data of the h day of trade of past；It is the summation of Gi, i takes the integer value greater than 0, i=1, and 2 ... ...
The number of n, n expression stock.Preferably, the mode of h days attention rates of user's self-selected stock is calculated are as follows: on T, to the stock i past h
Effective click of the day of trade (from T-1 to T-h) is summed, and G is obtained；When calculating G, using method of weighting, such as double remaining sum
Diminishing method is summed, in principle closer day of trade weight again after assigning different weights to effective click in T-1 to T-h
Bigger, remoter day of trade weight is smaller；The h day attention rate of stock i is calculated using above-mentioned calculation formula.
Specifically, the summation of effective click data is to ask the weighting of T-1 to T-h days effective click data
With, it sums again after assigning different weights to T-1 to T-h days effective click data, it is far and near according to the time from the T day of trade
Determine the size degree of weight.
Specifically, the calculation method of component stock weight is as follows:
In formula, qjIt is the weighted value of j-th of component stock, j=1,2 ..., m, m indicate the component stock in self-selected stock list
Number；Att (h, j) indicate to i-th of stock h-th of day of trade day attention rate；It is the summation of Att (h, j).
Specifically, the calculation method of the day free index is as follows:
In formula, T days indexes are index value of the free index on T；(T-1) day index is that free index refers in the day of T-1
Numerical value, as T-1=0, (T-1) day index takes the base period numerical value, such as the base period numerical value of free index is defined as N, takes N
=1000；Stock J is that amount of increase value from the 1st stock to j-th of stock on T sums it up in T days amounts of increase, qjIt is j-th
The weighted value of the component stock of stock, j=1,2 ..., m, m indicate the component stock number in self-selected stock list.
Specifically, the day of the day free index combination history free index is synthesized into day K line, the day K line is same as above
Card index is compared, and obtains the characteristic value of the component stock, the characteristic value mainly includes transaction value, market value, exchange hand, stream
Lead to any of drop man number of market value, the rise man number of real-time statistics, real-time statistics or appoints multiple values.
The establishment of the free index index new as one and the birth of correlation analysis method will be for A-share investor
The generation once innovated may become the product to pass from mouth to mouth between user in a very long time in later period, invest for investor
Decision provides certain comparison reference frame.Complete personality analysis, thousand people, thousand face, why cry free stock index be exactly because
The index be it is related to each user for having self-selected stock itself, there are 1,000,000 users just to have 1,000,000 free indexes, there is 100,000,000 strands
The people just have 100,000,000 free stock index, are truly realized personalized index, this currently on the market there are no the appearance of such index,
Free index realize the class index from having nothing；In order to more accurately react the tendency of the free index of user, certainly
It selects the range of index to define, mainly based on the A-share of Shanghai and Shenzhen, in addition when acquisition user effectively clicks, joined a variety of
Calculation and analysis methods, such as when calculating self-selected stock click summation according to user's service life, we use double declining
Method, i.e. T-1 to T-H day it is effective click assign different weights after sum again, the current closer day of trade weight of distance is bigger,
Such weight method makes calculated result more accurate；The personalization of free index is the analysis and calculating of mass data behind,
As soon as each user index, how many free index of how many stock invester need that the self-selected stock of user is formed slice daily
The correlation for carrying out T-1 days such self-selected stocks of upload calculating is clicked and weighted data, while the same day is needed again by the reality of the constituent stocks
When market amount of increase and amount of decrease get, calculate the amount of increase and amount of decrease of current time index in real time by formula, because of the individualized feature of index, service
End calculation amount has compared to common upper card composite or other theme indexes amplifies significantly；When free index calculates, the calculating that provides
Formula is to calculate the attention rate of user for a period of time using effective click of user first, calculates in conjunction with the attention rate of user
The weight of user finally calculates free index according to the amount of increase and amount of decrease of target stock, and the algorithmic formula is although relative complex, but by each
The setting of kind condition, can cover the scene of most users.
As shown in Fig. 2, front end shows the design of the existing great wisdom conventional indexes of combination after free index is worked out,
Show timesharing, K line number according to while can also list transaction value, exchange hand, market value, circulation, always buy, always sell etc. disks mouth data；Also
The characteristics indexs such as the unique funds flow of great wisdom can be merged, judged by the analysis of various indexs free index it is subsequent walk
Gesture；Index is combined closer with operation, and scalability is stronger, after free index birth, each has the user of self-selected stock to have oneself
Free stock index, each day of trade just have ups and downs and bear interest, all kinds of operation activities can be unfolded for free index in this way,
The high user of free index is ranked up, and the high user's self-selected stock synchronous sharing of income is come out, provides one kind for everybody
The reference selected stocks can also effectively be unfolded for the operation of free index in this way；Parameter adjustment flexibly, is adapted to different market rows
Feelings；Free index is not that market entirety index is done not in parameter for different market conditions because related to everyone
Same adjustment, does not influence global analysis of the user to market, and the opposite in due course adjustment by individual parameters can more reflect free
Stock stock most really shows, such as when the big rise and big fall of market, needs to reject the personal share of extreme performance outside, such as connect
The stock of a continuous word limit-up, limit down, because these stocks are unable to, actual response user's entirety self-selected stock is horizontal, at this time free
Index is with regard to inadequate reference value.
